Novell Novell TCP IP for

This belt covers Novell to live able to provide you with sufficient information to design a mixed network correctly. In most blended networks, you're going to seemingly approach upon NetWare as an existing working system on a community. Novell NetWare has gone through many alterations over the years. This piece compares and contrasts the predominant elements of releases 3.12, 4.0, four.11, and 5.0.

what is the change?

The default protocol supported in vulgar models of NetWare (excluding edition 5) is IPX/SPX. IPX/SPX is a proprietary protocol developed through Novell principally for NetWare. TCP/IP turned into an add-in product. (Microsoft implements a protocol referred to as NWLink IPX for compatibility with Novell servers.) This made it very difficult to design a mixed network. most of the time you were required to exercise a protocol gateway to span combined networks. although, with Microsoft's implementation of NWLink and Novell's exercise of the IP add-in, the assignment became a dinky less demanding.

Novell seen that almost vulgar network designers had been picking to reserve in accommodate TCP/IP as a routed protocol, so that they made some alterations to NetWare. Novell now uses TCP/IP because the default protocol for NetWare types 5 and higher.

while we're with regards to protocols, a different major trade to NetWare with version 5 is in the client. vulgar versions of NetWare ahead of edition 5 came bundled with a shopper utility known as Client32. Client32 turned into installed on the computer notebook and acted as an authentication agent for the Novell community. The problem become that Client32 used Novell's TCP/IP stack. (this is Novell's implementation of the protocol. now not vulgar implementations of the equal protocol are the identical beneath the hood.) When Client32 turned into reserve in on a desktop working a Microsoft operating system (the exercise of the Microsoft TCP/IP stack), the two IP stacks would regularly conflict. This made administration a really difficult job. directors would regularly find that classes written notably for the Microsoft IP stack would now not work as designed.

From an administrative standpoint, or not it's the dinky things that depend. for instance, the person setup reveal is comparable to that of Microsoft trade. The NetWare person reveal holds a myriad of suggestions tidbits equivalent to cell number and site. an additional minor but no less critical administrative change is the messenger. Did you ever exercise the route person a Message election in home windows NT Server? In 9 and a half years I even occupy under no circumstances gotten it to work. The messenger in NetWare truly works. Why is that so vital? if you would affection each person to log out the device for any intent (usually a gadget shutdown), the easiest method is to ship a message arrogate to their displays.

What's separate under the Hood?

As they now comprehend, the windows NT listing constitution is in accordance with domains. Your rights as a user rely on the domain you belong to. The listing employed by using Novell in versions of NetWare just before four.eleven become referred to as bindery. Bindery rights work in a similar vogue to belt rights in that the bindery the consumer is in determines his or her consumer privileges.

This changed in NetWare 4.eleven. Novell revolutionized the directory constitution market with the tree structure. Now NetWare domains are damaged down into contraptions, every one a bit larger than the one below it. every unit has its personal body of rights that cascades down to the instruments beneath but does not movement up. This capability that the uppermost unit might furthermore occupy a rule that says "users within the staff neighborhood can entry the rest," but three instruments down there could live a rule that says "Joe (who simply happens to live in the workforce group) can not entry the accounting extent." Sound everyday? or not it's the predecessor to Microsoft's dynamic directory.

This doc walks through how to configure SQL Mail for Microsoft SQL Server to work with Novell Groupwise. For the expostulate of this document i will check with the user account as sqluser and the password as sqlpassword.

necessities

you should occupy each Microsoft SQL Server and Groupwise reserve in. In my ambiance, I had SQL Server 2000 and Groupwise v6.5 reserve in on windows 2003 Server.

Configuration

There are four main steps to constructing your SQL Server to work with Novell Groupwise.

user Setup

you are going to deserve to create a [specific user] sqluser who has three money owed - a Novell Login, Novell GroupWise Login, and home windows Login. live sure that each one three are the equal identify and password. as an specimen i assume handicap of sqluser with sqlpassword for vulgar three. build sure that sqluser is a piece of the directors group beneath windows.be aware: After finishing this step you must login beneath your fresh account for the remaining steps.

service Setup

exchange each the MSSQLSERVER and SQLSERVERAGENT features to exercise the .\sqluser account and password.

Mail Setup

make sure you are logged in below sqluser otherwise your mail settings should live flawed. Open the Mail applet in the manage Panel. you'll want to occupy already got a Novell Default Settings profile. beneath properties you are going to notice a list of features associated with the profile. opt for Novell GroupWise Message store and deem the properties.

under management, view the residences for SQL Server Agent. provider Startup Account belt should still occupy .\sqluser and sqlpassword stuffed in. If Mail Session is grayed out it's because your SQL Server Agent service is not vulgar started, live sure to birth it and are available again to the residences window. Mail profile should still occupy Novell Default Settings selected. it is going to interrogate if the SQL Server Agent provider can restart, click ok to restart the provider.

opt for the Operators belt below SQL Server Agent. Create a fresh Operator, in case your Novell Default Settings profile had the Novell Groupwise address e-book listed below its provider you may live in a position to exercise the addressbook at this factor to peep up emails. that you could pick to select the consumer from the addressbook or you can simply classification in an electronic mail address on the line. after you occupy a electronic mail tackle click on the check button. it'll interrogate you to authenticate your verify. click safe enough. build sure to now notice “The message become despatched efficiently.”

Congradulations SQL Mail now work!

Troubleshooting
test Hangs SQL Server

for the judgement that Microsoft SQL Server runs as a provider it connects to Novell GroupWise through a "hidden" virtual computing device. this may occupy the repercussion of making it materialize to live SQL Server is hung when the GroupWise initialization prompts for more information such as the person's password. If this happens the most likely problem is your Command Line settings. build sure you didnt occupy a typo or flawed settings.

To peep at various your command line goto windows Command Line and type perquisite here instance.

note: If groupwise loads devoid of prompting for additional information then your command line is suitable.

check Fails to ship e-mail to Operator

The verify button appears to disregard the chosen profile beneath SQL Server Agent and as a substitute operates in opposition t the default mapi profile. It may well live necessary to set the selected profile as the default profile. this is now not an argument if you only occupy the Novell Default Settings profile.

No exploit reserve for Operators

The most likely vicissitude is that you shouldn't occupy Novell Groupwise tackle e-book provider setup for the Novell Default Settings mail profile.

Mail Session is Grayed Out

SQL Server Agent service isn't working. once you start the carrier you'll want to live in a position to return to the houses and change the mail session.

SQL Mail has an void Profile list

what's happening is SQL Server appears on the mail settings for the person linked to MSSQLSERVER carrier. if you occupy local tackle account set for the consumer to elope the carrier it will no longer know what mail settings to build exercise of. another judgement may well live that should you setup your mail profile you occupy been no longer logged in to home windows below your sqluser account and the changes the space associated to the wrong user. live sure that sqluser is set to elope the MSSQLSERVER service. as soon as each the mail profile and MSSQLSERVER carrier are set to elope with sqluser you should definitely notice the profiles listed once more beneath SQL MAIL.

Your issue now not Listed

if you are unable to ascertain the error you're having or occupy elope into an extra error you occupy got solved tickle believe free to e mail me at chris dot shepherd at gmail dot com and i could live satisfied to respond any questions and / or supplant this documentation.

frame Relay and the Novell IPX SuiteNovell IPX implementations over frame Relay are corresponding to IP network implementation. Whereas a TCP/IP implementation would require the mapping of Layer three IP addresses to a DLCI, Novell IPX implementations require the mapping of the Layer 3 IPX address to a DLCI. particular consideration has to live made with IPX over frame Relay implementations concerning the repercussion of Novell RIP (distance-vector algorithm) or NLSP (NetWare link capabilities Protocol, hyperlink-state algorithm) and SAP (provider advertising Protocol) message traffic to a frame Relay internetwork.

body Relay IPX Bandwidth GuidelinesIPX can devour big quantities of bandwidth very at once by handicap of its broadcast announcement-based design. Following are some issues that display some find out how to accept as precise with to manage the IPX traffic and slit its occupy an repercussion on on a body Relay WAN.

To in the reduction of overhead in a body Relay community, invoke the Burst Mode NetWare Loadable Module (NLM). Burst Mode opens the IPX window to evade expecting one acknowledgement (ACK) per IPX packet, and permits a highest window of 128.

one more consideration is the implementation of the colossal cyber web Packet change (LIPX) NLM if no longer edition four.X or better. LIPX will allow for larger-sized packets between customer and server. (often within the case of frame Relay WANs, the customer and server can live connected via frame Relay VC.) native IPX devoid of LIPX allows for a optimum payload frame measurement of 512 bytes; LIPX extends the packet measurement to a thousand to 4000 bytes. The larger packet size consumes much less processing energy from the frame Relay entry devices, in flip increasing throughput.

word: as a result of Ethernet and Token Ring LANs aid better body sizes, the native IPX 512 byte body hassle has an adverse effect on network throughput across WAN routers.

if you are working with an older version of Novell NetWare (v3.11), invoke the NLSP NLM for network routing. NLSP handiest sends routing information when an undergo happens (hyperlink failure) or each two hours. The commonplace RIP [routing] protocol sends its whole routing desk to vulgar different routers every 30 seconds. NLSP uses less bandwidth over the WAN, guaranteeing greater bandwidth is accessible for user records site visitors.

note: SAP utilizes IPX packets to broadcast or promote obtainable capabilities on a NetWare LAN. NetWare servers exercise these SAP packets to advertise their tackle, features available, and denomination to vulgar consumers each 60 seconds. vulgar servers on a NetWare LAN listen for these SAP messages and deliver them in their own server counsel desk. as a result of most Novell customers build the most of native resources, the elements should live advertised on a local foundation and not broadcast throughout the frame Relay WAN.

This tip, from mikeshardware.com, helped me resolve an issue with a flaky Windows XP install:

Every experienced network guru knows that quite often the problem with a faulty network connection is due to the TCP/IP stack being corrupted or not properly bound. Starting with WinXP, Microsoft has disabled the capacity to uninstall TCP/IP. So what are you to enact if you suspect that vulgar that is needed is a spotless install of the TCP/IP stack? Luckily, it is fairly facile to rebuild the stack to the pristine conditions that it was in on a spotless install using the NetShell utility.

The only inequity between these two is that the first will create the log in the current directory while the second specifies where the log is to live created. After creating the log you can exercise Notepad or any other text editor to notice exactly what changes were made.

This chapter describes the TCP/IP protocol system and shows how the components of TCP/IP work together to route and receive data across the network.

This chapter is from the reserve 

TCP/IP is a system (or suite) of protocols, and a protocol is a system of rules and procedures. For the most part, the hardware and software of the communicating computers carry out the rules of TCP/IP communications—the user does not occupy to rep involved with the details. Still, a working information of TCP/IP is essential if you want to navigate through the configuration and troubleshoot problems you’ll countenance with TCP/IP networks.

This hour describes the TCP/IP protocol system and shows how the components of TCP/IP work together to route and receive data across the network.

At the completion of this hour, you will live able to

Describe the layers of the TCP/IP protocol system and the purpose of each layer

Describe the layers of the OSI protocol model and clarify how the OSI layers relate to TCP/IP

Explain TCP/IP protocol headers and how data is enclosed with header information at each layer of the protocol stack

Name the data package at each layer of the TCP/IP stack

Discuss the TCP, UDP, and IP protocols and how they work together to provide TCP/IP functionality

Before looking at the elements of TCP/IP, it is best to inaugurate with a brief review of the responsibilities of a protocol system.

A protocol system such as TCP/IP must live answerable for the following tasks:

Dividing messages into manageable chunks of data that will pass efficiently through the transmission medium.

Interfacing with the network adapter hardware.

Addressing: The sending computer must live capable of targeting data to a receiving computer. The receiving computer must live capable of recognizing a message that it is supposed to receive.

Routing data to the subnet of the destination computer, even if the source subnet and the destination subnet are dissimilar physical networks.

Performing error control, flood control, and acknowledgment: For reliable communication, the sending and receiving computers must live able to identify and redress faulty transmissions and control the flood of data.

Accepting data from an application and passing it to the network.

Receiving data from the network and passing it to an application.

To accomplish the preceding tasks, the creators of TCP/IP settled on a modular design. The TCP/IP protocol system is divided into separate components that theoretically function independently from one another. Each component is answerable for a piece of the communication process.

The handicap of this modular design is that it lets vendors easily adjust the protocol software to specific hardware and operating systems. For instance, the Network Access layer (as you learn in Hour 3, “The Network Access Layer”) includes functions relating to the specification and design of the physical network. Because of TCP/IP’s modular design, a vendor such as Microsoft does not occupy to build a completely different software package for TCP/IP on an optical-fiber network (as opposed to TCP/IP on an ordinary ethernet network). The upper layers are not affected by the different physical architecture; only the Network Access layer must change.

The TCP/IP protocol system is subdivided into layered components, each of which performs specific duties (see motif 2.1). This model, or stack, comes from the early days of TCP/IP, and it is sometimes called the TCP/IP model. The official TCP/IP protocol layers and their functions are described in the following list. Compare the functions in the list with the responsibilities listed earlier in this section, and you’ll notice how the responsibilities of the protocol system are distributed among the layers.

Network Access layer: Provides an interface with the physical network. Formats the data for the transmission medium and addresses data for the subnet based on physical hardware addresses. Provides error control for data delivered on the physical network.

Internet layer: Provides logical, hardware-independent addressing so that data can pass among subnets with different physical architectures. Provides routing to reduce traffic and support delivery across the internetwork. (The term internetwork refers to an interconnected, greater network of local belt networks (LANs), such as what you find in a big company or on the Internet.) Relates physical addresses (used at the Network Access layer) to logical addresses.

Transport layer: Provides flow-control, error-control, and acknowledgment services for the internetwork. Serves as an interface for network applications.

Later hours provide more particular descriptions of the activities at each of these TCP/IP protocol layers.

When the TCP/IP protocol software prepares a piece of data for transmission across the network, each layer on the sending machine adds a layer of information to the data that is germane to the corresponding layer on the receiving machine. For instance, the Internet layer of the computer sending the data adds a header with some information that is significant to the Internet layer of the computer receiving the message. This process is sometimes referred to as encapsulation. At the receiving terminate these headers are removed as the data is passed up the protocol stack.

It is sometimes useful to know the network commands to resolve or configure your TCP/IP networksHere is the list of commands that can live used in the command prompt:
Ping
PING: Test the network connection with a remote IP address
ping-t [IP or host]
ping-l 1024 [IP or host]
The -t option to ping continuously until Ctrl-C is pressed.If you specify the -t option you can always rep statistics without interrupting pings by pressing Ctrl + Break

This command is furthermore useful to generate network load by specifying the size of the packet with the -l option and the packet size in bytes.

Tracert
TRACERT: Displays vulgar intermediate IP addresses through which a packet passes through, between the local machine and the specified IP address.
